4 ETD STA JOSEPH SHAW GAUNT AND HARRY DYSON, OF MANCHESTER, ENGLAND.

SPINDLE OF SPINNING AND LIKE MACHINES.

Application filed May 10, 1917.

To all whom it may concern:

Be it known that we, JOSEPH SHAW GAUNT and HARRY DYsoN, of Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements Connected with the Spindles of Spinning and like Machines, of which the following is a specification.

The object of this invention is to simplify the method of securing a cup or flier to the race of a ball bearing and to render the flier more easily detachable than heretofore.

According to this invention an annular groove preferably of semi-circular section is formed on the inner side of the lower cylindrical hollow lip of the cup or flier and immediately below the bottom edge or face of the outer ring of the ball race on which 7 the flier is mounted.

one half section of which enters the above mentioned groove in the cup, the other half section pro ecting immediately underneath the lower face of the outer ring of the ball race, thus preventing the removal of the cup from its place until the wire has been dis placed. To facilitate the removal of the wire an opening is formed in the lower part of the cup so as to interrupt a portion of the groove and expose a portion of the wire, to permit the application of a displacing instrumentality.

These details will now be described with reference to the accompanying drawing.

The drawing represents partly in section and partly in elevation the usual ball race composed of a fixed inner ring P, and a rotary outer ring 4, (said rings being separated by interposed balls as usual), an ordinary fixed support to which the inner ring is attached and on which the outer ring is confined against sidewise displacement, and the cup or .flier 2 which is of ordinary form and construction, excepting as hereinafter specified. The lower cylindrical hollow lip 2 of the flier is formed internally to removably embrace the outer ring 4 and to project below the latter. The projecting lower portion of said lip is provided with an internal Specification of Letters Patent.

Serial No. 167,679.

groove 1, preferably of semi-circular section and located below and in close proximity to the lower edge of the outer ring 4.

3 represents a resilient retaining wire parti ally and removably embedded in the groove 1 and of such diameter that its inner surface projects inwardly from the inner surface of the lip 2 and forms a shoulder adapted to abut against the ring 4: and prevent the removal of the flier from said ring. When the wire 3 is removed, the flier may be moved upwardly and separated from the ring.

The lip 2 is provided with an opening 5, formed to interrupt a portion of the groove 1 and expose a portion of the wire 3, so that any suitably formed displacing instrumentality may be applied to the wire to force it from the groove 1 and permit the removal of the cup or flier.

Claims:

1. A cup or flier, for use with an annular ball race composed of a fixed inner ring and a rotatable outer ring which is confined against sidewise displacement, said cup or flier having a cylindrical hollow lower lip, formed internally to removably embrace said outer ring and project below the latter, the projecting portion of said lip being provided with an internal groove, and a resilient retaining wire partially embedded in said groove and projecting inwardly to form a shoulder adapted to prevent the removal of the flier from the outer ring, said wire being removable to permit the removal of the flier.

2. A cup or flier as specified by claim 1, the said lip being provided with an opening interrupting a portion of said groove and exposing a portion of said Wire to permit the application of a displacing instrumentality to the wire.

In testimony whereof we have affixed our signatures in presence of two witnesses.
